COMPLETIi relaxation of the limbs is always possible when sleeping on an inflated bed. 
All regular types of air-beds are too bulky and cumbersome for general Active Service use. 
The "Bolmat " is just the size to accommodate head, shoulders, hip and knee. The bolster 
cannot come adrift, and total size when rolled, i8in. long by 4in. diameter, permits its use in 
Trench, Dug-out or Camp. Rapidly inflated by the mouth, ground sheet unnecessary, 
Cramp, Stiffness and damp avoided.

REMARKABLE SUCCESS OF SIMPLE AND INEXPENSIVE INVENTION 
WHICH SAVES SCUTTLES UPON SCUTTLES OF COAL 
Driscoll's Incandescent Fire Mantle Replaces Coal, but does not Alter Appearance 
ef Fire. Does not Requite any Special Installation, Alteration, or Treatment of Fuel 
NO invention of recent times has Iwen received with greater pleasure or has gained such rapid universal recognition and approbation 
as DrLscoU's Incandescent Kire Mantle, which saves coal and increases heat. It is a device of special design, which is simply phiceil 
into the centre of any grate. It »ciei:tificall_v ulilisea the heat tnergy created by the combustion of coal, which, instead of fiving up 
the chimney, as is the case with the larger portion of such ener<;y in ordinary grates, is made to bring the mantle to incandescent heat. 
Thus there lies in the centre of the fire an enormously hot mass, throwing out more heat than coal alone can give, vet absolutely unburnablc 
and as good at the end of twelve months as it is the first day. The appearance of the fire is in no wav alt red ; the mantle is compJetelv 
covered by the .snrronnding coal, and its presence cannot be detectid. XO IXST.\LLATIOX, ALTKR.ATIOX, or SPECIAL TRE.\TMKXt 
OF THE FUEL OH THE GRATE IS XECK.SS.AHY. There is iiu niurring ex|KMiditure of any kind ; when once you have purchased the 
fire mantle you can enjoy for ever a beautifully bright and hot fire at an enormous saving of coal. The mantle is placed into the grate with 
ex.-i^tly as much^and no more — trouble than it is to put on a lump of coal. It requires no attention or care of any kind. 
EXTREME SIMPLICITY. 
As with most really clever inventions, the particiJarly surprising part of Driscoll's Incandescent Mantle is its extreme simplicity. There 
is nothing complicated about its construction or operation, nothing to get out of order or to require constant careful supervision. It is as 
simple as coal itself — takes the place of coal and increases the heat— but while coal burns away the mantle remains, everlastinslv savin" 
fuel. • b J . . - 
REMARKABLE TEST FIGURES. 
.As the result of a recently restricted .^(ipervisf'd test upon miiilcin grates, it was found that the average i«nsumption of coal per 
giat« in the ordinary grate (eight grates were experimented upon in this particular test) was 341b. of coal for a period of eleven hours. 
On the following day one of the new fire mantles was placed in each of these same grates, and the coal consumption per grate for ;i 
period <•! twelve hours was then found to have been reduced to !9lli. 3oz., whilst the heat was greater. 
BEWARE OF IMITATIONS. 
The universal success of the Incandescent Fire Mantle has led to several imitations being oflfered to tlie public. In some eases even 
the wording and general arrangement of the advertisements of the Incandescent Mantle C;)mpany are so closily followed that it seems 
necessary to insist upon this point in order to prevent confusion between the genuine Ihnniiighly tested Incandescent Fire Mantle an I 
other devices. The Incandt'scent Fire Mantle does not interfere with the ordinary laying of the fire, and does not prevent poking the fire 
It is constructed on strictly .scientific lines and produces its great money.saving clfect bv niore (oniplete conibuslidii of the coal and by ceneratii 
far gieater heat for any given quantity of fuel. 
SAVES ITS COST IN A FEW DAYS. 
The price of the Incandescent Fire Mantle is 3s, (3s. 9d. post free), which small sum is saved back in a few davs The mantle last^
